We discovered a cone shaped nebula that has an opening angle of about
90° and extends eastward of the IR source 2MASS J19142564+1109283,
which is very likely a massive young stellar object (MYSO). This
morphology suggests a cavity that was cleared in the circumstellar
material, and its emission may arise from scattered continuum light,
warm dust, and probably also from emission lines from shock-excited
gas. The nebula, which presents arc-like features, is connected with
the IR source through a jet-like structure, which is aligned with the
blueshifted CO outflow found in a previous study.
